Hi,
we are using a triaxial accelerometer which generated 26KByte of information in a single axis for 1 sec. so for 3 axis, it is 26K*3=78kB. we have reached a bottleneck of internal memory in the controller. I would like to know the possible ways to use external memory with faster processing capabilities. we have thought about external spitypebased ram but that speed is not sufficient. we need to do the data acquisition, filtering, and fast Fourier transform on board itself. we are using RSL10 controller from on semi. any inputs/guidance is much appreciated.

Thanks,
Ashok
